36  * 1. "head" buckets are the ones allocated in the array of buckets in qht_map.
37  * 2. all "non-head" buckets (i.e. all others) are members of a chain that
38  *    starts from a head bucket.
39  * Note that the seqlock and spinlock of a head bucket applies to all buckets
40  * chained to it; these two fields are unused in non-head buckets.
174  * @buckets: array of head buckets. It is constant once the map is created.
175  * @n_buckets: number of head buckets. It is constant once the map is created.
176  * @n_added_buckets: number of added (i.e. "non-head") buckets
373  * Get a head bucket and lock it, making sure its parent map is not stale.
